ASSET integrates ScanWorks with Teradyne's PXI Express instruments
Embedded instrumentation tools supplier, ASSET InterTech, and automatic test equipment developer, Teradyne, have extended the integration of the JTAG and boundary-scan test capabilities of ASSET’s ScanWorks platform for embedded instruments into Teradyne’s PXI Express-based High Speed Subsystem (HSSub).
Last year, ASSET and Teradyne collaborated to integrate ScanWorks into Teradyne’s VXI-based Di-Series instruments, which are widely deployed in large-scale test systems in defense/aerospace, such as the Teradyne Spectrum 9100 and Lockheed Martin’s LM-STAR.
Now the companies are collaborating again, this time to integrate software-based ScanWorks tools with Teradyne’s HSSub which provides support for custom and standardised high-speed digital buses in new or legacy test systems deployed in the defense and aerospace market.
As a result, users of these ATE systems with PXI Express-based instruments will have immediate access to the cost-effective and robust boundary-scan and JTAG test and programming solutions on the ScanWorks platform.
“Making the extensive boundary-scan and JTAG capabilities of ScanWorks available to circuit board manufacturers and defense contractors reduces their tests costs and test times significantly over the entire life cycle of a product,” said Kent Zetterberg, ASSET’s product manager for ScanWorks boundary-scan test tools. “For example, tests developed on a standalone ScanWorks platform during the product design phase will shorten and simplify prototype board bring-up significantly."
"Later, those same tests can migrate with the design when it moves into manufacturing where the same tests can be easily re-used, eliminating test development costs for the manufacturing organisation. And later in the life cycle, in repair and maintenance depots, those same tests can be re-used again to debug and troubleshoot boards," he adds. "So, the cost of test is reduced significantly over all phases of the product’s life cycle. For programs stretching over several years, the savings can be substantial.”
ScanWorks was integrated into Teradyne’s HSSub through its Boundary Scan Runtime Library (TERBSR), a software facility that gives access to several of its instrument families through an application programming interface.
As a result of the integration, the boundary-scan and JTAG tools are able to test a circuit board through the high-speed communications channels on a Teradyne instrument. These channels connect ScanWorks to the boundary-scan Test Access Port on the circuit board that’s being tested.
